tion of the invention, such as will enable' others skilled in the art towhich it appertains to make and use the same.

In constructing a sand-box according to my invention I employ twocastings for each pair of wheels, each tapering to a nozzle end, towhich is attached an india-rubber or other pipe to convey the sand tothe rails. These castings are bolted tothe ioor of the tramcar or othervehicle in a position suitable to the gage of the rails. Holescorresponding to the size of the sand-box are cut in the floor, overwhich hoppers are fixed in such a position as to get a direct fall forthe sand. The inside face of the casting is removable and attached tothe main casting by bolts or otherwise in order to form a detachabledoor. The interior of the casting is formed so as to admit anoscillating tumbler with a square hole, and when sand is required thishole is brought to van upright position by suitable mechanism vand whenshut off assumes a horizontal position, thus preventing the sand fromrunning to waste. The tumbler works on a spindle, one end of whichprojects through the main casting and the other through the detachabledoor above mentioned. To the portion of the spindle on the outside ofthe casting a pin is attached which works in a boss on the castingformed to allow the tumbler to open fully and close. To the spindleworking through the door is attached a crank xed to a bar carrying asimilar crank at its other end, this latter crank beingjitted to acrossbar spaced to the. samegage as the boxes. Near the center of theplatform, where the car-driver stands, a loose pin passes through thefloor and lies in a hole in a crank attached to the center of thecross-bar before mentioned. The cranks fixed to the spindles in theboxes are held in position by strong spiral springs fastened to theframework of the car, so that the sand is shut off or turned on normalposition,shut.ing ed the sand.' '.Each sand-box may be made to workindependently of the other, if this is required, by disconnecting thecrank which controls thatl box which it is not desired to use. A I

In order that my said invention may be better understood, Iwill nowproceed to describe the same with reference to the drawings accompanyingthis specification, in which- Figure 1 shows plan of sand-box; Fig. 2,j

elevation of inside face; Fig. 3, end view; Figs. 4,. 5, and 6, detailsof tumbler; Figs. 7 and 8, cover detached; Fig. 9, details hereinafterreferred to; Fig. 10, plan'showing general arrangement; Fig. 1l, sectionat B, Fig. 10; Fig. 12, section at C D, Fig. l0. Figs. 10, 11, and 12are drawn to a smaller scale than the other figures.

The same letters of reference are employed to denote the same parts inall the views. Y

a shows main casting with nozzle end b. This casting is bolted to thefloor of the car, as shown at Fig. 11. Holes corresponding tothe size ofthe sand-box are cut in the floor. Over the casting ct a hopper c isxed.

d shows a detachable door or face attached tothe main casting. v

e` is an oscillatingtumbler mounted onthecasting a, as shown. Thistumbler e is formed with a square hole f and may be turned to allow sandto pass, as in the position shown at Fig. 3, or may be turned to blockthe passage of sand or to any desired intermediate posi` tion. Thetumbler e works onY the spindleg, one end of which projects through themain casting and theother through the detachable door d.

h shows pin attached tothe spindle g. Thism is fitted to a bar "n,spaced to the same gage as the boxes'.

o shows a loose pin passing through the floor near the center' of theplatform and resting under the recess in one end of the crank p, fixedon the cross-bar a.

q shows spiral spring fastened to l[he framework of the car and by meansof a chain to the crank j.

The driver by actuating with his foot the loose pin o turns the tumblere, so that the sand is turned on or off, as required. The tumbler e mayin the same manner be turned partially instead of completely.

fr 7', Fig. 2, show two pieces of rubber or other material placed inslots the full width of the tumbler, so as to prevent leakage frombetween the tumbler and the main casting.

What I claim, and desire to secure by Letters Patent of the UnitedStates of America,

l. In a sanding-box, the combination with a main casting, provided witha hollow chamber therethrough, a hopper above said chamber, a detachabledoor forming one side of said casting and chamber, an oscillatingtumbier mounted in said chamber, journaled to one of the side wallsthereof and said detachable door, and provided with an aperturetherethrough adapted to Communicate with the delivery end of saidhopper, and means for oscillating said tumbler.

2. In a sanding-box, the combination with a main casting, provided witha hollow chamber therethrough, a hopper above said charnber, anoscillating tumbler, having an aperture therethrough and provided withspindles jonrnaled in said casting, means for oscillating said tumbler,a boss on said casting, and a pin on one of said spindles engaging saidboss for limiting the oscillation of said tumbler.

3. In a sanding-box, the combination with a main casting, provided witha hollow chamber therethrough, a detachable door, a delivery-nozzlelocated below said chamber, a hopper above said chamber', an oscillatingtum bler, mounted in said chamber, having an apertu re therethrough,adapted to communicate with the delivery end of said hopper and saiddelivery nozzle, means for oscillating said tumbler, a boss on saidcasting, a pin carried by said tumbler, adapted to engage said boss forlimiting the oscillation of said tumbler, and rubber bushings extendinglongitudinally of said tumbler for preventing leakage between thetumbler and said casting.

In testimony whereof I aix my signature in presence of two witnesses.

JOHN VILLIAM ENDEAN.
